Indian paintbrushes are wildflowers native to the Mediterranean and cultivated globally. They are edible and used to season soups, salads, pickles, sauces, meats, and stews. They are also used to make tea and to flavor beer, liquors, bitters, and Chartreuse. In 1933, it was deemed unlawful to pick Indian paintbrushes in Texas without specific permission, though this law was repealed in 1973. It is currently unlawful to pick flowers growing on the right of way of any public highway in Idaho.

What You'll Learn
Indian paintbrushes are edible flowers
Indian paintbrushes, also known as Castilleja, are a genus of about 200 species of annual and perennial plants native to the west of the Americas from Alaska south to the Andes, northern Asia, and as far west as the Kola Peninsula in Russia. They are classified in the broomrape family Orobanchaceae.
Indian paintbrushes are indeed edible flowers, though they are known to have toxic properties. Native Americans used this species in both food and poison. The showy red structures are technically bracts, a type of modified leaf, and not petals. The actual flower petals are greenish-yellow and rather inconspicuous, though the tips of the sepals are tinged with red.
The plants are hemiparasitic, relying on other plant species, and are an important food source for the larvae of some lepidopteran species, including certain checkerspot butterflies. The foliage of some Indian paintbrush species contains defensive compounds that are sequestered in the tissues of larvae of specialist insect species that have developed a tolerance and are able to consume the foliage.
In terms of legality, there are laws in some states, such as Idaho and Texas, that prohibit the picking of flowers, including Indian paintbrushes, on public land or land maintained by the state. However, these laws may have specific exemptions for landowners, their agents, or employees.

Indian paintbrushes are parasitic
Indian paintbrushes, also known as Castilleja, are native perennial, annual, or biennial herbs of North America. They are parasitic plants that rely on other plants for survival. They are root hemiparasites, which means they can produce some of their food through photosynthesis but also depend on other plants for additional nutrients. They have special roots called haustoria, which attach to the roots of their host plants and extract nutrients from them. This process is known as parasitism, and it allows the Indian paintbrush to survive and thrive.
Indian paintbrushes have a strong relationship with their host plants. They commonly parasitise plants like little bluestem, penstemons, and prairie blue-eyed grass. In some regions, they also parasitise lupine, a member of the bean family that has a symbiotic relationship with nitrogen-fixing bacteria. By parasitising lupine, Indian paintbrush gains increased access to nitrogen, resulting in better growth, increased reproduction, and enhanced pollen output. This relationship highlights the complex dynamics between Indian paintbrush and its host plants.
The parasitic nature of Indian paintbrushes has a significant impact on the community structure of plants. As a root hemiparasite, Indian paintbrush can benefit greatly from parasitising a dominant species in a plant community. While it gains limited advantages from a secondary species, its presence can reduce the fitness of the dominant species, affecting the overall competition for resources. This dynamic showcases how the introduction of Indian paintbrush can shift the balance in plant communities.
Indian paintbrushes are known for their brightly coloured bracts, which can be red, orange, yellow, or even shades of pink and violet. These colourful bracts stand out in contrast to the insignificant, tubular, greenish-yellow flowers nestled within them. The bracts are responsible for giving the Indian paintbrush its name and are also believed to have medicinal properties. The plant's ability to absorb selenium in certain areas, such as Colorado, has been linked to cases of toxicity, highlighting the importance of understanding the parasitic nature of this plant.
While Indian paintbrushes are parasitic, their legal protection varies across different regions. For example, under a 1933 law in Texas, it was unlawful to pick Indian paintbrushes or other wildflowers on enclosed land or land maintained by the state without specific permission. However, with the codification of the 1973 Penal Code, this old statute was repealed. In Idaho, it is unlawful to wilfully and negligently pick any plant, flower, or vegetation growing upon the right of way of any public highway within the state. These laws highlight the legal considerations regarding the protection of Indian paintbrushes and other vegetation.

Indian paintbrushes are toxic to cattle
In the state of Idaho, it is unlawful for any person to wilfully and negligently cut, dig up, trim, pick, or remove any plant, flower, shrub, bush, fruit, or other vegetation growing upon the right of way of any public highway within the state. However, this law does not apply to employees of the federal government or the state of Idaho who are engaged in work on public roads or highways.
In Texas, a 1933 law stated that it was unlawful to pick any flowers, including Indian paintbrushes, on enclosed land or land maintained by the state as a public park or preserve without specific permission. This law was repealed with the codification of the 1973 Penal Code. While there may not be specific laws prohibiting the picking of Indian paintbrushes, it is important to note that these plants could be protected under other legislation or local ordinances.
Now, regarding the toxicity of Indian paintbrushes to cattle, it is important to understand the potential risks. Indian paintbrushes (Castilleja species) are indeed toxic to cattle and other livestock. The toxicity is primarily associated with the presence of a glycoside called castillejoside, which can cause severe liver damage and even death in affected animals. Cattle are particularly susceptible to the toxic effects of Indian paintbrushes due to their grazing habits and tendency to consume large quantities of vegetation.
Indian paintbrushes are most toxic when they are in the flowering stage, as this is when the castillejoside concentration is at its highest. However, the plants can still be toxic during other growth stages, especially if consumed in significant quantities. The toxicity varies depending on the specific Castilleja species, as well as the individual animal's tolerance and the amount ingested. Some species, such as Castilleja integra, are known to be highly toxic, while others may have milder effects.
Symptoms of Indian paintbrush poisoning in cattle include loss of appetite, weight loss, jaundice (yellowing of the skin and eyes), lethargy, and diarrhoea. In severe cases, affected cattle may experience liver failure and death. There is currently no specific antidote for Indian paintbrush poisoning, so prevention is crucial. Livestock owners and farmers should take measures to prevent their cattle from grazing in areas where Indian paintbrushes are prevalent, especially during the flowering season.
If Indian paintbrush poisoning is suspected, it is important to seek veterinary assistance immediately. Treatment typically involves supportive care, including intravenous fluids, nutritional support, and, in severe cases, liver transplantation. By taking proactive measures and being vigilant, livestock owners can help protect their cattle from the toxic effects of Indian paintbrushes and ensure their overall health and well-being.

Indian paintbrushes were once illegal to pick in Texas
Indian paintbrushes, along with bluebonnets and other wildflowers, were once illegal to pick in Texas. A 1933 law stated that it was unlawful to pick any flowers on enclosed land or land maintained by the state as a public park or preserve without specific permission. This law was repealed with the codification of the 1973 Penal Code.
Indian paintbrush is the name of several edible flowers native to the Mediterranean but now cultivated globally. One variety, Castillija linariaefolia, is considered the best-tasting in its genus. The blossoms are usually added to salads or made into syrup, while the bitter-mint oil is used to flavour beer, liquors, and bitters.
In some places, picking certain types of flowers is still illegal. For example, it is unlawful to cut, dig up, trim, pick, or remove any plant, flower, shrub, bush, fruit, or other vegetation growing on the right of way of any public highway in Idaho. Similarly, in Maine, Mayflowers, also known as Trailing Arbutus, are illegal to pick in some places, although it is not clear if this is specific to certain areas or more general guidance.
The legality of picking flowers, including Indian paintbrushes, therefore, depends on the location and the type of land. While it may no longer be against the law to pick Indian paintbrushes in Texas, it is important to check the local laws before foraging for any wildflowers to avoid potential legal consequences.

It is illegal to pick plants on public highways in Idaho
In Idaho, it is illegal to pick plants on public highways. Section 18-3911 of the Idaho State Legislature states that it is unlawful for any person to "wilfully and negligently cut, dig up, trim, pick, or remove, any plant, flower, shrub, bush, fruit or other vegetation growing upon the right of way of any public highway within this state." This law is in place to protect the wildflowers and natural vegetation of the state from needless destruction and waste.
It is important to note that this law does not apply to employees of the federal government or the state of Idaho who are engaged in work on public roads or highways. Additionally, it does not apply to the owners of land or their agents if the vegetation in question is declared a public nuisance.
The transportation and sale of certain native wildflowers and shrubs are also prohibited by this law. It is unlawful to export, sell, or transport bulbs, corms, rhizomes, roots, or plants of these protected species. This includes plants that have been dug up or gathered from any highway.
While the law specifically mentions Indian paintbrushes as protected in Texas, there is no specific mention of Indian paintbrushes in the Idaho legislation. However, the law in Idaho does refer to "native wildflowers" and "other vegetation", which could potentially include Indian paintbrushes depending on the context and location. It is important to respect the natural environment and follow local laws and regulations regarding the picking of any plants, including Indian paintbrushes, when on public highways or other protected areas.
